"1940" Headstamped .50 BMG


#1

I have seen a poor photo of a fired .50 BMG case which from what I can see, simply has the headstamp “1940” at 12 O’Clock.

I have never seen anything like this before. Does anyone recognise the headstamp I am talking about just from the description?

Thanks for any info.

The only headstamp that I can think of is the Remington headstamp for 12.7 x 99 rds loaded primarily for Great Britain during WW II>

RA1940 (from 10:00 to 2:00)
.50 CAL Z (from 8;00 to 4;00)

Can we be sure the cartridge case is a .50 Browning and not–for example–a 13.2 m/m Hotchkiss? I ask the question since we’re evidently working from a third party identification and a poor photographic image. Jack

Thanks for the responses. I have spoken to the owner of the case. It appears that the case head has been filed. It now seems that this was likely an RA round.
